⚛️Draft Regulatory Guide for Probabilistic Fracture Mechanics

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment Revision 1 to draft Regulatory Guide (DG), DG-1422, "Preparing Probabilistic Fracture Mechanics Submittals." This DG is proposed Revision 1 to Regulatory Guide (RG) 1.245, "Preparing Probabilistic Fracture Mechanics Submittals." DG-1422, Revision 1, describes a framework to develop the contents of a licensing submittal that the staff of the NRC considers acceptable when performing probabilistic fracture mechanics (PFM) analyses in support of regulatory applications.
